NOVELTY - The utility model claims a 0.8D ultra-fine denier terylene hollow short fiber a hollow polyester a short fiber layer and a carbon layer fiber the outside of the core is covered with a water-soluble superfine denier terylene layer, the water-soluble superfine terylene layer is provided with a hollow terylene short layer fiber the hollow terylene short layer fiber provided with a carbon layer fiber the carbon layer fiber provided with a flame-resistant ultra-fine denier terylene short layer fiber the outer side of the flame-resistant superfine denier terylene short fiber layer is provided with a graphene fiber, the graphene fiber outer side is provided with anti-pilling ultra-fine denier terylene fiber the water-soluble superfine denier terylene layer and the hollow terylene short-fiber layer, the hollow polyester the short, the short fiber the carbon fiber the carbon fiber and the anti-burning superfine denier terylene short layer fiber fixedly connected through the aqueous laminating glue. It can improve the high temperature resistance of the polyester fiber, corrosion resistance, and has strong functionality.
